CALF-WEANER.

Specification of Letters Patent.

Application filed July 17, 1914. Serial No. 851,433.

To all whom it may concern:

Be it known that 1, WILLIAM A. CoBBAN, citizen of the United States,residing at Culbertson, in the county of Sheridan and State of Montana,have invented certain new and useful Improvements in Calf-Weaners; and

I do hereby declare the following to be a full, clear, and exactdescription of themvention, such as will enable others skilled in theart to which it appertains to make and use the same.

My invention has for its object to provide a calf weaner; and, to thisend, it consists of the novel devices and arrangement of partshereinafter described and defined in the claim.

In the accompanying drawings, which illustrate the invention, likecharacters indicate like parts throughout the several views.

Referring to the drawing, Figure l is a perspective View of the improvedweaner, applied in operative position to the nasal septum of a calf;Fig. 2 is a perspective view of the improved weaner, on an enlargedscale; Fig. 3 is an edge elevation of the same; and Fig. 4 is aperspective view, corresponding to Fig. 2, but showing the lock pin inan inoperative position.

The numeral 1 indicates a guard plate, having in one of its longitudinaledges a notch 2, adapted to embrace the nasal septum of a calf Z. Thenotched longitudinal edge of the guard plate 1 is rolled to aiford apair of axially alined seats 8, on opposite sides of the notch 2.

A lock pin 4, for securing the guard plate to the nasal septum oi? thecalf, is slidably mounted for endwise movement in the seats 3. This lockpin 4, when moved into both of the seats 3, extends across the notch 2and its outer end is bent laterally at 5 and terminates in a hook 6.Formed in the guard plate 1 is a perforation 7, into which the hook 6 isadapted to be inserted, under a slight springing action of the laterallybent end 5 of the lock pin, for holding the lock pin in an operativeposition. The guard plate 1 is preferably formed of sheet metal, and thelock pin 4 formed from a steel wire having a slight spring therein.

To apply the improved weaner in an operative position, the lock pin 4:is moved into a position as shown in Fig. 4:. The guard plate 1 is thenapplied to the nasal septum of the calf so that said nasal septumextends into the notch 2. The lock pin 4 is now moved into a position asshown in Fig. 2, which movement punctures the nasal septum and therebysecurely locks the device to the calf. Obviously, the device may bereadily applied to or removed from the calf, at will.

What I claim is:

A calf weaner, comprising a guard plate having a notch in one edgeadapted to embrace the nasal septum, the notched edge of said guardplate being rolled to afi'ord a pair of alined seats on opposite sidesof said notch, and a lock pin, slidably mounted in said seats formovement through said notchand through the nasal septum, one end of saidlock pin being laterally bent and terminating in a hook adapted to entera perforation in the body of said guard plate, under a spring action,for holding said pin in an operative position.

In testimony whereof I afliX my signature in presence of two witnesses.

WILLIAM A. COBBAN.
